The result isn't just devastating for the Greens.

Without the Greens, on this poll, Labour wouldn't have the numbers to form a coalition Government with New Zealand First and the Māori Party.

In the lead-up to the election, the Greens have struggled to deal with both internal and external challenges.

Inside the party, Metiria Turei's admission of benefit fraud saw two senior MPs quit their list positions in protest. Ms Turei then stood down from co-leadership herself, followed by two senior staffers.
